tors, of which the following is a specification,"

reference being had therein to the accompany- IO ing drawings.

This invention relates to the peculiar construction of cash register andindicator seen in Letters Patent No. 349,522, granted to William G.Schickner September 22, 1886;

I and the first part of our improvements comprises a novel combinationof secondary bell.- cranks and triggers for operating the rest-bar thatsupports the elevated tabletstems, as hereinafter more fully described.

The second part of our improvements comprises a novel resettingmechanism,as hereinafter more fully described.

.The third part of our improvements coinprises a novel combination ofdevices which prevents the operation of either of the keys after. themoney-drawer has been opened, thereby rendering it impossible toregister another amount untilsaid drawer is again closed, which actrestores all the keys to their normal positions, as hereinafter morefully described.

In the annexed drawings, Figure 1 is a ver" tical section of ourimproved cash register and indicator, one of the keys of the same beingshown depressed, so as to elevate a tablet and .35 initiate the openingof the money-drawer, the

lifter of said tablet being supported upon the rest-bar. Fig. 2 is anenlarged section of a portion of the machine, showing one of the keyslocked, so as to be inoperative. Fig. 3 is a transversesection of aportion of the machine, showing all the keys locked. Fig. 4 is anenlarged front elevation of one of the primary disks, the shaft uponwhich it is journaled being sectioned. Fig. 5 is a vertical section ofsaid disk. Fig. 6 is an enlarged section of a portion of the same. Fig.7 is an elevation of a modification of the resetting mechanism. Fig. 8is a plan of tlie same. Fig. 9

is an enlarged elevation of a portion of the machine, one of thesecondary bell-cranks being shown in its normal position. Fig. 10 is asimilar elevation, but showing the aforesaid bell-crank as having justcompleted 1ts extreme rearward swing. Fig. 11 is a rear elevation of aportion of the machine. Fig. 12 5 shows the locks at the ends of theshafts of the primary-and secondary disks. Fig. 13 is an enlargedvertical section through the bearings of the main and secondarybell-cranks.

A represents the case or cabinet of the regis- 6 ter and indicator;a,thelid; a a, the windows, and B the money-drawer, which latter 1ssituated'below a horizontal partition, C, of said case.

d is a shaft that serves as a bearing for the upper and lower banksofkeys,D and D, whose outer ends are provided with the customarybuttons, (1, while their inner ends traverse the vertical slots 6 of afixed plate or grat1ng, E. Supported upon these keys and traversing saidslots are the free ends of a set of llfters, F, one for each of the keysthe other or front ends of said lifters being hung upon a fixed bar, f.Furthermore, the rear or free ends of said lifters project some distancebeyond the extremities of the respective keys, for a purpose that willpresently appear. Maintained in contact with the upper edges of thekeysby a spring, 9, or otherwise, is a horizontal bar,

G, uniting the long arms HH of a pairo f precisely-similar bell-cranks,H H H, the shorter arms of which, H H, PIOJGCD down through slots 0 ofpartition C and carry rollers h, adapted to bear against the rear end ofthe money-drawer B every time a key 18 operated. Located at the junctionof these arms H H of the main bell-cranks are hubs h, journaled upon thespindles-e of grating E,and these hubs serve as bearings for the hubstof the secondary bell-cranksfl I l l,who'se upper andlonger no arms, II, are connected by the rest-bar J.

K K are the triggers, pivoted at k to the long arms H H of the mainbell-cranks, and having catches k, that engage at the proper moment withthe free ends of the shorter arms, 5 I I. of thesecondary bell'cranks.

L are springs that cause the triggers to engage with said arms, and Lare other springs interposed between said triggers and arms for thepurpose of restoring the secondary bell- 10o cranks to their normalpositions, and,-if desired, the action of these springs L may besupplemented by other springs, L, arranged as shown in Fig. 1 or as seenin Figs. 9 and 10.

Z are stop-pins that limit the motion of triggers K K, and Z are otherstops, that prevent the secondary bell-cranks swinging too far in caseall the tablet-stems should be raised at once.

Z are trips for operating the triggers, said trips being usuallythumb-screws tapped into suitable bearings projecting from the sideplates of the machine,in order that the action of the trigger may beregulated to suit ciroumstances.

m are the tablet-stems,which stems traverse suitable guides, at, andcarry at their upper ends the customary tablets, M.

N is a gong or bell adapted to be struck by a hammer, a, attached toeither of the long arms I or 1 of the secondary bell-cranks.

O O are the shafts of the primary and secondary disks, the outer ends ofsaid shafts being provided with square arbors 0 0. (Seen in Fig. 12.)These arbors are designed for the reception of an ordinary winding-keyor socket-wrench, and have secured to them disks 0, the periphery ofeach disk being notched at 0 to admit teeth 19 p at the lower ends oflevers P P, the latter being pivoted to the case at p", and beingcoupled together by a spring, P, that maintains said teeth in contactwith said disks.

Q and Q, are the primary and secondary disks, adapted. to revolve freelyupon their respective shafts O O, and as these disks are alike adescription of one will answer for all, reference to Figs. 4, 5, and 6showing their details very clearly. The front face of each disk isperfectly fiat, except where an annular flange, q, and the end of thehub project therefrom, while the back of the disk is chambered out at qto afford room for the pin of the adjacent disk. annular space betweenthis flange g and hub by a screw, 7', or otherwise, is a plate-spring,R, whose free end inclines outwardly at r, is then furnished with a flatextension, 1", passing through a slot, q, of the disk, and finallyterminates with a lip, 1".

S represents a ratchet-wheel fitting snugly around the raised. annularflange q, and secured to the disk by suitable fasteners, as s, so as tobe readily adjusted to said disk.

T are pins projecting from the shafts O 0'; but said pins may besupplanted by a lug, t, projecting from a washer, T, which washer has atongue, t, that enters a longitudinal groove, 0, of said shafts.

U is a double-ended spring for preventing retrograde turning of thedisks.

Uis a feed-pawl that operates the primary disk Q, and U is a spur thatcommunicates motion from thelatterto the secondary disk Q.

V is a curved plate inclosing the operating mechanism, and having slots12 'v to permitthe dials being inspected.

Z is a spring attached to a bar, 2. and engaging with alug, a, offeed-pawl U, thereby Secured within the holding the latter in contactwith the ratchetwheel S, and also assisting in elevating the front endof the key D.

c are slots in the partition 0, to permit a free swing of bell-cranksWW, which cranks are suitably pivoted within the case,and their upperarms carry a lock-bar, to, extending completely across the machine, asseen in Fig. 3. The lower arm of bell-crank W may have a small roller,10, journaled therein, which roller normally occupies a pocket, X, inthe side board of the drawer, the rear end of this pocket terminatingwith an inclined shoulder, or. Furthermore,the side boards of the drawerare shod with half-round metallic runners Y Y, that slide upon hardbearings y, the latter being usually formed of staples driven into thebottom of the case, as seen in Fig. 11.

When our cash register and indicator is in its normal position, theoperative parts of the same are disposed as seen in Fig. 9, theextremity of key D resting within the slote and supporting the free endof lifter F, which lifter sustains the tablet-stem m. Furthermore, inthis normal position of the machine the rod G, uniting the long arms H Hof the principal bell-cranks, bears directly upon all the keys, and thestress of springs L and L swings the arms 1 I of the secondarybellcranks forward until the rest-bar J comes in contact with thetablet-stems, while at the same time the springs L cause the triggers KK to engage with the ends of the shorter arms, I I, of these secondarycranks. The drawer B is shoved back into the case and the bellcranks W Wassume the positions seen in Fig. l, the roller w of said crank beingnow quite near the front end of pocket X, thus leaving all the keys freeto be operated. The moment either of the keys is depressed theconnecting-bar G is elevated, thereby causing the operative parts toassume the position seen in Fig. 1, but more clearly shown in Fig. 10.It is apparent this elevation of said bar causes the principalbell-cranks H H H H to turn on the spindles c of the grating E, by whichact the rollers h advance the drawerB aslight distance, said drawerbeing first unlocked by suitable internal devices that are automaticallybrought into service, the locking appli' ances seen in Schicknerspatent, No. 349,522, being preferred for this purpose. This swing of theprincipal bell-cranks causes a corresponding movement of the secondarybellcranks, I l I I, because the latter are now locked to the former bythe spring-triggers K K; but the moment the lifter raised by the key Dreaches the top of slot 6 said triggers come in contact with the tripsZ", thereby disengaging said triggers from the short arms I l of thesecondary bell cranks, as seen in Fig. 10. The springs L and L instantlyrestore these bell-cranks to their normal positions, thus bringing therest-bar J in under the free end of lifter F while the key D is fallingdown to its original position. The raised tablet remains in thiselevated position upon the lifter IOC ' until one or more keys areoperated, and

' when this occurs the weight of said tablet and stem depresses the freeend of said lifter as soon as the restbar J again reaches the positionseen in Fig. 10. The arrow in this illustration shows the are describedby the free end of the lifter and indicates the clearance between thelatter and the rest-bar.

From the above description it is apparent that the rest-bar J acts muchmore promptly than it would do if the arms I I were rigidly united tothe bell-cranks H H H H. Owing to the location of the feed-pawl U andthe shape of the ratehet-teeth S, it is evident the primary disk Q mustrevolve in the direction of the single-headed arrow seen in Fig. 4, and

as the shaft 0 is locked the inclined portion rof spring R must come incontact with the pin T at every revolution of said disk,therebygradually compressing this portion of said spring, as indicated by thedotted lines in Fig. 6. The free end of the spring is accordingly forcedtoward the face of the disk until said spring escapes from contact withthe pin,when the spring at once regains its normal position.Consequently said pin offers no resistance to the proper turning of thedisk; but when the disk is to be reset or turned around to the zeromarkthe pin is brought into service, preparatory to which act the lever P isswung over in the direction of the arrow seen in Fig. 12, therebydisengaging'the toothp from the notch o. A key is then applied to thearbor 0 and shaft 0 is turned in the direction of the double headedarrow seen in Fig, 4, which act brings the pin T in contact with thefiat extension 9 of spring R, and thus turns the disk Qaround until itszero or starting point is directly under the slot 22. This act isrepeated until all the primary disks have been reset, and then thesecondary disks are'reset in a precisely similar manner after the tooth12 has been disengaged from the notch 0" of the other arbor, 0. Thedrawer B is opened by the rollers h it only aslight distance, as seen inFig. 1, and then it must be pulled out by hand to obtainany moneycontained therein, which complete opening of the drawer causes theinclined shoulder 00 of the pocket X to come in contact with the wheelto of the bell crank W. This actswings the short arm of the bellcrank upto the position seen in Fig. 2, thus causing the bar to to bear againstthe under side of all the keys, as represented in Fig. 3.

By this arrangement the bar to serves as a lock that prevents any of thekeys being operated until the drawer is shoved in and the bellcranks W Ware allowed to assume their norhard bearings 3/ enables the drawer to beadvanced by the rollers hwithout exerting a severe pressure upon theoperating-keys D of the register and indicator. Finally, by making theratchet-wheels S separate from the disks Q Qand attaching them to thelatter with screws or other convenient fastening-s, 3, said wheels canbe readily adjusted for the purpose of getting the teeth exactly in linewith the numbers on said disks.

WVe claim as our invention" 1.
